Application filed April 7,

This invention relates to rotary dyeing machines, and the rincipal object of the invention is to provi eja cylinder so constructed as to be free from all sharp edges and 6 projections in the interior compartments which mightinjure the fabrics.

The invention further resides in the novel Y details of construction which render the c linder easily manufactured and assemb ed and very strong. and durable.

the cylinder has a unitary structuralfeature making possible standardization of parts and the development from these parts of cylinw ders of varying lengths and containing different num ers of compartments for reception of the articles to be dyed.- j

In the attached drawings: Fi re 1 is a longitudinal section through a cylinder made in accordance with my invention; Fig. 2. is a section on the line 2-2, Fig. 1;' Fig. 3 is a section on the line 3-3, Fig. 2; Fig. 4 is a section on the line 4-.4, Fig. 2; Fig. 5' is a section on the line 5-5, Fig. 2; "Fig. 6 is a wow in'perspective showing a. fra mentary' assembly;

ig. 7 is a fragmentary section showing a detail ,of the construction; H Figs.*8, 9, 10, 11,-12," and 13, are detached perspectives illustratingelements of the construction, and Fig. 14 is a fragmentaryperspective of one of the longitudinal partitions; M

With reference to the drawings, the cylin der comprises the usual centralcylinder-su porting shaft 1. having near each endv a co lar 2 which, in each instance, constitutes an abutment for an end plate 3. The said end plates 3 are in each instance confined be tween the said collars 2 and a gear wheel 5 carried by the shaft 1, 'and'the outer ends of the shaft are threaded for the reception of nuts 6, 6, which in assembly are'screwed' downagainst the'hubs of. the gears. Each of the face plates"'3"ha's'a jperipheral lateral flange 7 to which are secured by means of rivets 9, arcua t'e plates lqforming a cylinder Wan 1L I The shaft'lis provided, in the resent instance, with three longitudinal ra ial grooves 12, 12 in which are,sea'tedthe inner edges of three perforated partitioning plates 13 which divide the interior of the'cylinder into three main longitudinal compartments. The end with two recesses 19 which 1925. Serial in. 21,381.

'and thereby 'secure the said gears to the ends of the cylinder and also confine between I the end lates and the gears the inner ends 68 As a further novel feature of advantage,

of the c annels 17 The inner ends of the bars 14 closely fit the shaft 1' while the outer ends preferab y bear neatly against the inner face of the cylinder wall 11.

Eachof the partitionin plates '13 is, in the '70 i present instance, provide at its inner edge are adapted tov fit over and into radial grooves, 21, in a. pair of hub elements 22, 22 on the shaft 1. Each of these hub elements 22 is also pro- 7 vided with a peripheral groove 23 adapted to receive the inner arcuate edge-24 of segmen tal partitioning plates 25, shown in per spective in Fig. 9. The side edges of these partitioning segments 25 occupy longitudinal grooves 26 in radial bars 27 and 28 respectively, the bars of each pair thereof bemg adapted to lie.respectively on opposite sides of thelongitudinal partitioning plates 13 with their inner ends occupying recesses 29-29 in-the said hub elements 22, as clearl illustrated in Fig. 6. Each ofthe bars 2 is provided with dowels which extend through the apertures in the partitions 13 and enter holes formed for their reception in 00 the bars 28, the dowels functionin to maintain the bars in position during t e operation of the assembly. By means of the segmental partitions 25, each of the main lon tudinal chambers of the cylinder formed y 06 the partition plates 13, 13 :is divided, in the present instance, into threeunifprmly sized sgb-compartments of generally segmental s ape.

The outer edges of the segmental plates 25 occupy ooves 32 in curvilinear bars 33. mounts on the inside of the segmental cylinder plates 10 and thesebars 33 are secured in place bymeans of studs 34 which project through the perforations in the said cylinder plates 10 and through segmentalbars 35 thereby securing both these latter bars and the bars 33 in place. The bars 35, as shown in Fig.2, in each instance extend from one of the main partitions 13 to a point shortof an adjacent partition as clearly shown inFig. 2, and are'so shaped at the outside that when .a guide plate 36 is placed on top and secured in place by means of f the aforesaid studs 34, a channel 37 is proignated in Fig. 2 by the reference numeral 38. are adapted-to be closed by means of a door 39 whose side edges occupy the aforesaid grooves 37 and similar grooves 41 in a bar 42 held by rivets 9 to the flanges of the end plates 3. The bars 42 comprise the base 43. a spacer element 44 and the outer guide plate 45. the groove 41 being formed between the inner face of this guide plate 45 and the outer .face of the base 43 b reason of the interposed spacer 44. As shown in Fig. 2. each of the plates along one edge of the opening 38 is hooked over to engage the oppositely hooked edge 46 of the sliding door 39 and the end of each of the plates 36 is turned down as indicated at 47 to form a stop limiting the opening travel of the door 39 in its guide grooves.

Also as shown in Fig.2. each of the partitions -l3 proiccts beyond the c linder wall 11 and has welded. thereto the flanged edge 48 of oneof the cylinder plates 10. This pro ecting joint is covered over and hidden b a bentover strip 49 which embraces the edges of the plate 10 and the partition 13 and also the upstanding flange of an angle bar 50 secured to the opposite side of the partition 13.

As shown in Fig. 5. the studs 34 are slotted at their inner ends for the reception of the plates 25 whereby the said studs are prevented from turning. It will also be noted that both the lateral partitions 25 and the longitudinal. partitions 13 are perforated to allow free circulation of the dyeing medium through the articles confined in the chambers. i

It will be notedthat in the present instance there is shown no bolt or rivet extending into the chambers which hold the fabrics, the surfaces of these chambers being accordingly free from all inward projections which might present a sharp edge or part to injure the fabrics. Also, the parts may be utilized with various lengths of the cylinder plates 10 to provide any desired length of cylinder having any required number of chambers, the parts, with the exception of the cylinder plates and longitudinal partitions being standard for each diameter of cylinder.

I claim: 1. A cylinder for dyeing machines comprising a shaft, circular end plates secured to the shaft, a cylindrical shell secured to the end plates, longitudinal partitions extending radially from the shaft and dividing the interior of the cylinder into a plurality of compartments, segmental transverse partitions, and slotted members fitted to the said longitudinal partitions and to the shell and forming frames for reception of said transverse partitions. 1

2. A cylinder for dyeing machines comprising a shaft, circular end plates secured to the shaft, slotted members secured to the inner faces of said end plates. radial plates each having one longitudinal edge fitted into a longitudinal groove in the shaft and the end edges in the said slotted members, arcuate plates secured at their edges to the outer edges of said radial plates and to the end plates, segmental transverse partitioning plates, and slotted members fitted to the said longitudinal partitions and to the shell and forming frames for reception of said transverse partitions.

3. A cylinder for dyeing machines comprising a shaft having a plurality of longitudinal slots, circular end plates secured to the shaft in spaced relation; an annular element on the shaft intermediate the end plates. said element being slotted transversely in alignment with the said shaft slots and also circumferentially, slotted elements secured to the inner faces of the end plates and extending radially from the shaft. longitudinal partitioning plates seated in the said radial slotted elements and in the aligned slots of the shaft and annular element, slotted elements fitted to the said partitioning plates and extending radially from the shaft with their slots in alignment with the circum- 7 ferential slot of said annular member,
